BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a ventilating apparatus and, more particularly, to a ventilating unit and a ventilating top construction for a building, such as a factory and the like.

2. Description of the Related Art

A conventional ventilating apparatus comprises a plurality of motor fans mounted on the roof of a building to carry away the hot air in the building so as to lower down the temperature in the building. However, the motor fans consume a lot of electric power, thereby increasing the cost of the ventilating apparatus. In addition, the motor fans project outward from the building, thereby decreasing the aesthetic quality of the building. Another conventional ventilating apparatus comprises a plurality of sprinklers mounted on the roof of a building to provide a heat dissipation effect to the building so as to lower down the temperature in the building. However, the sprinklers consume a lot of electric power, thereby increasing the cost of the ventilating apparatus. In addition, the sprinklers project outward from the building, thereby decreasing the aesthetic quality of the building.

BRIEF SUMMARY OF THE INVENTION

The primary objective of the present invention is to provide a ventilating unit and a ventilating top construction for a building.

According to the primary objective of the present invention, the hot air in the building is rapidly drained outward from the upper board through the vent holes of the ventilating board of each of the ventilating units so that each of the ventilating units of each of the roof assemblies provides a heat radiating effect to the building to lower down the temperature in the building.

According to another objective of the present invention, the hot air in the building rises to pass through the gap of the base and the vent bores of the ventilating plate into the upper cover plate and is carried outward from the upper cover plate by a heat convection so that the hot air is rapidly drained outward from the vent bores of the ventilating plate of the ridge assembly to lower down the temperature in the building.

Preferably, each of the two lower boards 2 is an elongate sheet plate and has a substantially U-shaped cross-sectional profile.

The ventilating board 3 of each of the ventilating units 90 has two opposite sides each provided with an extension 31 abutting the respective oblique portion 10 of the upper board 1. The extension 31 of the ventilating board 3 is combined with an inner face of the respective oblique portion 10 of the upper board 1. The ventilating board 3 of each of the ventilating units 90 has a surface provided with a plurality of vent holes 30. Some of the vent holes 30 of the ventilating board 3 are connected between the upper board 1 and each of the two lower boards 2, and some of the vent holes 30 of the ventilating board 3 are connected between the upper board 1 and a gap 22 defined between the two lower boards 2.
